SHARED OR DEDICATED SERVER SESSIONS, WHICH IS BETTER FOR AN OLTP SYSTEM?

edited Oct 27, 2011 9:06AM in Database Administration (MOSC) 7 comments
Application unable to acquire new connection to the database. Error No managed connection picked up from the application log.
We have services deployed across 11 application servers (running JBoss Application server) which are connected to a 2 node RAC database.
DB Parameter sessions is set to 6605. Each application server is configured to use around 900 connections to the database.

We observed that most of the time applications sessions are always idle, so we configured the middle ware to use shared server instead of dedicated.
Now all are our services are performing very slowly.

What is the best way to configure shared servers for an OLTP based system?

Howdy, Stranger!
